Urgent help onw lower timing chain

[Keep it clean]

My lower timing chain broke and am considering whether to fix it or buy a new ka. I can get the parts for cheap and do labor myself so it will come out way cheaper to fix but my issue is when the lower timing chain breaks on a 1995-96 ka24de, do the pistons collide with the valves resulting in internal damage in which i would have to take the head to the machine shop or do they have a semispherical shape that prevents damage like this to be done. Im not sure if my car has that extra clearance so that the pistons dont collide with the valves. PLEASE HELP ASAP

The KA is an interference engine. Most likely there will be valve damage to the heads.

thnx. parts are not worth buying even if i do the labor myself so im ending up buying a 98' ka to put in the 95 body. Ill just end up building the damaged ka into a powerful engine with more care and time
